	to show that they can be different. Clean up mkfs, simplifying specifying fs parameters, remove some redundancy between fs and mkfs, and fix disk layout bugs. Call blocks in the file system blocks instead of sectors. Passes usertests for different block sizes.
2011-08-29	Revert "Introduce and use sleeplocks instead of BUSY flags"	Frans Kaashoek
	My changes have a race with re-used bufs and the code doesn't seem to get shorter Keep the changes that fixed ip->off race This reverts commit 3a5fa7ed9020eaf8ab843a16d26db7393b2ec072. Conflicts: defs.h file.c file.h
2011-08-26	Introduce and use sleeplocks instead of BUSY flags	Frans Kaashoek
